  • Alcatel-Lucent: Enterprise 2.0: The Top 5 Things I would Do Over

    - by Kellsey Ruppel
    Happy Monday! Does anyone else feel as if the weekend went entirely too quickly? At least for those of us in the United States, we have the 4th of July Holiday next week to look forward to This week on the blog, we are going to focus on "WebCenter by Example" and highlight best practices from customers and partners. I recently came across this article and I think this is a great example of how we can learn from one another when it comes to social collaboration adoption. Do you agree with Jem? What things or best practices have you learned in your organizations?  By Jem Janik, Enterprise community manager, Alcatel-Lucent  Not so long ago, Engage, the Alcatel-Lucent employee social network and collaboration platform, celebrated its third birthday. With more than 25,000 members actively interacting each month, Engage has been a big enough success that it’s been the subject of external articles, and often those of us who helped launch it will go out and speak about what aspects contributed to that success. Hindsight is still 20/20 and what it takes to successfully launch an enterprise 2.0 community is fairly well-known now.  Today I want to tell you what I suspect you really want to know about.  As the enterprise community manager for Engage, after three years in, what are the top 5 things I wish we (and I mostly mean me) could do over? #5 Define your analytics solution from the start There is so much to do when you launch a community and initially growing it without complete chaos is quite a task.  It doesn’t take too long to get to a point where you want to focus your continued efforts in growing company collaboration.  Do people truly talk across regional boundaries or have we shifted siloed conversations to a new platform.  Is there one organization that doesn’t interact with another? If you are lucky you’ll have someone in your community team well versed in the world of databases and SQL queries, but it takes time to figure out what backend analytics data actually means. Professional support can be expensive and it may be hard to justify later as it typically has the community manager as the only main customer.  Figure out what you think you’ll want to know and how to get it early on. The sooner the better even if it doesn’t seem that critical at the time. #4 Lobbies guide you to the right places One piece of feedback that comes up more and more as we keep growing Engage is it’s hard to find stuff, or new people are not sure where to start. Something we’re doing now is defining some general topic areas of interest to be like “lobbies” into the platform and some common hashtags to go with them. I liken this to walking into a large medical or professional building for the first time.  There are hundreds of offices, and you look to a sign in the lobby to get guided to the right place for you.  We’re building that sign for members now, but again we missed the boat as the majority of the company has had their initial Engage experience. #3 Clean up, clean up, clean up Knowledge work and folksonomies are messy! The day we opened the doors to Engage I would have said we should keep everything ever created in Engage with an argument that it was a window into our collective knowledge so nothing should go.  Well, 6000+ groups and 200,000+ pieces of content later, I’ve changed my mind.  As previously mentioned, with too much “stuff” the system can be overwhelming to new members and it makes it harder to get what you’re looking for.   Do we need that help document about a tool we no longer have? NO!  Do we need that group that had 1 document and 2 discussions in the last two years? NO! Should we only have one group about a given topic instead of 4?  YES! Last fall, Engage defined a cleanup process for groups not used for a long time.  We also formed a volunteer cleaning army who are extra eyes on the hunt for “stuff” that should be updated, merged, or deleted.  It’s better late than never, but in line with what’s becoming a theme I wish these efforts had started earlier. #2 Communications & local community management One of the most important aspects of my job is to make sure people who should be talking to each other are actually doing it.  Connecting people to the other people they should know, the groups they should join, a piece of content that shouldn’t be missed.   I have worked both inside and outside of communications teams, and they are the best informed people in your company.  They know when something big is coming, how it impacts employees, how it fits with strategy, who else knows more, etc.  Having communications professionals who are power users can help scale up community management because they are already so well connected.  They also need to have the platform skills to pay attention without suffering email overload, how to grab someone’s attention, etc.  I wish I’d had figured this out much earlier.  If I had I would have groomed more communications colleagues into advocates and power members right at the start. #1 Grooming advocates vs. natural advocates I’ve just alluded to this above already. The very best advocates are those who naturally embrace your platform and automatically start to see new ways to work within it.  Those advocates seem to come out of the woodwork naturally since some of them are early adopters.  Not surprisingly, our best advocates today are those same people who were willing to come kick the tires when the community was completely empty.  Unfortunately, we didn’t get a global spread of those natural advocates.  I did ask around when we first launched for other people who might be good candidates, but didn’t push too hard as there were so many other things to get ready.  That was a mistake.  If I could get a redo I would have formally asked for people to be assigned where there were gaps and groomed them into an advocate.  Today as we find new advocates to fill the gaps, people are hesitant as the initial set has three years of practice are ahead of the curve power members; it definitely would have been easier earlier on. As fairly early adopters to corporate scale enterprise collaboration, there hasn’t been a roadmap to follow as we’ve grown Engage, which is part of the fun! It’s clear a lot of issues are more easily tackled the earlier you identify and begin to correct them, and I’ve identified the main five I wish I could redo.  In the spirit of collaboration, I hope someone else learns from my mistakes!

  • OSI Model

    - by kaleidoscope
    The Open System Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model. A layer is a collection of conceptually similar functions that provide services to the layer above it and receives service from the layer below it. Description of OSI layers: Layer 1: Physical Layer ·         Defines the electrical and physical specifications for devices. In particular, it defines the relationship between a device and a physical medium. ·         Establishment and termination of a connection to a communications medium. ·         Participation in the process whereby the communication resources are effectively shared among multiple users. ·         Modulation or conversion between the representation of digital data in user equipment and the corresponding signals transmitted over a communications channel. Layer 2: Data Link Layer ·         Provides the functional and procedural means to transfer data between network entities. ·         Detect and possibly correct errors that may occur in the Physical Layer. The error check is performed using Frame Check Sequence (FCS). ·         Addresses is then sought to see if it needs to process the rest of the frame itself or whether to pass it on to another host. ·         The Layer is divided into two sub layers: The Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. ·         MAC sub layer controls how a computer on the network gains access to the data and permission to transmit it. ·         LLC layer controls frame synchronization, flow control and error checking.   Layer 3: Network Layer ·         Provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks. ·         Performs network routing functions, and might also perform fragmentation and reassembly, and report delivery errors. ·         Network Layer Routers operate at this layer—sending data throughout the extended network and making the Internet possible.   Layer 4: Transport Layer ·         Provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. ·         Controls the reliability of a given link through flow control, segmentation/de-segmentation, and error control. ·         Transport Layer can keep track of the segments and retransmit those that fail. Layer 5: Session Layer ·         Controls the dialogues (connections) between computers. ·         Establishes, manages and terminates the connections between the local and remote application. ·         Provides for full-duplex, half-duplex, or simplex operation, and establishes checkpointing, adjournment, termination, and restart procedures. ·         Implemented explicitly in application environments that use remote procedure calls. Layer 6: Presentation Layer ·         Establishes a context between Application Layer entities, in which the higher-layer entities can use different syntax and semantics, as long as the presentation service understands both and the mapping between them. The presentation service data units are then encapsulated into Session Protocol data units, and moved down the stack. ·         Provides independence from differences in data representation (e.g., encryption) by translating from application to network format, and vice versa. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems. It is sometimes called the syntax layer. Layer 7: Application Layer ·         This layer interacts with software applications that implement a communicating component. ·         Identifies communication partners, determines resource availability, and synchronizes communication. o       When identifying communication partners, the application layer determines the identity and availability of communication partners for an application with data to transmit. o       When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists. o       In synchronizing communication, all communication between applications requires cooperation that is managed by the application layer.

  • Atheros AR9485 wireless card doesn't work in an ASUS K53E

    - by John
    I just installed Ubuntu 11.10 32-bit version in dual boot mode on an ASUS K53. Every thing seems to work fine except for the wireless. The wireless works on Windows 7. Ubuntu finds the wireless card, but it does not appear to be turned on. The only physical means of turning on the card is the FN-F2 key combo. That works on Windows, but not in Ubuntu. I've looked in the forums for a solution and I'm not quite sure what to do.

  • Getting a stream back from a .Net remoting service that is accessible with IP v4 and v6

    - by jon.ediger
    My company has an existing .Net Remoting service that listens on a port, fronting interfaces used by external systems. This all works great with IP v4 based communications. However, this service now needs to support both IP v4 communications and IP v6 communications. I have found info that the system.runtime.remoting section of the app.config should include two channels as follows: <channel ref="tcp" name="tcp6" port="9000" bindTo="[::]" /> <channel ref="tcp" name="tcp4" port="9000" bindTo="0.0.0.0" /> The above config file changes to the System.Runtime.Remoting config section will get the remoting service responding to non-stream functions on both ip v4 and ip v6. The issue comes only when attempting to get a stream back, used to upload or download large files. In this case, instead of getting a usable stream back, the following ArgumentException is thrown instead: IPv4 address 0.0.0.0 and IPv6 address ::0 are unspecified addresses that cannot be used as a target address. Parameter name: hostNameOrAddress Is there a way to modify the app.config (in the system.runtime.remoting section, or another section) so that the service will return a stream mapped to a real ip so the client can actually upload/download files while maintaining the ability to use both IP v4 and IP v6?

    I am using a Cisco 6500 series with an SSO redundancy configuration. The show redundancy output is as follows: Hardware Mode = Duplex Configured Redundancy Mode = sso Operating Redundancy Mode = rpr Maintenance Mode = Disabled Communications = Up I would assume the device is operating in RPR mode although SSO is configured. What could cause this? Shouldn't the operating mode be SSO? EDIT (show redundancy states): my state = 13 -ACTIVE peer state = 4 -STANDBY COLD Mode = Duplex Unit = Primary Unit ID = 5 Redundancy Mode (Operational) = rpr Redundancy Mode (Configured) = sso Redundancy State = rpr Split Mode = Disabled Manual Swact = Enabled Communications = Up client count = 60 client_notification_TMR = 30000 milliseconds keep_alive TMR = 9000 milliseconds keep_alive count = 1 keep_alive threshold = 18 RF debug mask = 0x0

  • RS-232 vs. RS-485

    - by user60524
    Doing a little research on the two to figure out which one may better suit my purposes (communications amongst different hardware). How do they fare against one another? Im far from being a specialist and have no idea where I would even start looking for data to compare and contrast. If possible can someone please answer the following questions in regards to each of these. Can they be networked amongst each other? Can they be easily networked over ethernet? What speeds do they transfer at? (Min, Max, Etc.) Reliability? Best framework to build on top of to support the above? Any standard communications programs? Debugging capability? Any help would be very much appreciated, thanks.

  • Private VOIP network

    - by SuppositoryPlacebo
    I own a small private security services business. Some of my clients require 2-10 security officers per location. I'm trying to think outside the box in order to solve my communications problem. I'd rather not buy or lease hf radios or voip systems at the current rates. I'm wondering if there is an existing system, or if is at all possible, to setup a private communications network using only a server and bluetooth devices or a wifi/bluethooth combination. http://25.media.tumblr.com/tumblr_m44f0pn7BL1rwp6tgo1_1280.png I don't need "radio" per se. I just need a simple, private voip network. Is there an existing device that consists of nothing more than a wifi adapter to control a bluetooth device?

  • What is the Sarbanes-Oxley (SOX) Act?

    In 2002 after the wake of the Enron and World Com Financial scandals Senator Paul Sarbanes and Representative Michael Oxley lead the creation of the Sarbanes-Oxley Act. This act administered by the Securities and Exchange Commission (SEC) dramatically altered corporate financial practices and data governance. In addition, it also set specific deadlines for compliance. The Sarbanes-Oxley is not a set of standard business rules and does not specify how a company should retain its records; In fact, this act outlines which pieces of data are to be stored as well as the storage duration. The SOX act targets the financial side of companies, but its impacts can be seen within the technology arena as well because it is their responsibility to store all of a company’s electronic records regardless of file type. This act specifies that all records and electronic messages must be saved for no less than five years according to SearchCIO. In addition, consequences for non-compliance are fines, imprisonment, or both. Sarbanes-Oxley Act: Rules that affect the management of Electronic records according to SearchCIO. Allowed practices regarding destruction, alteration, or falsification of records. Retention period for records storage. Best practices indicate that corporations securely store all business records using the same guidelines set for public accountants. Types of business records that need to be stored Business Records  Business Communications Including Electronic Communications References: SOXLaw: The Sarbanes-Oxley Act 2002 Retrieved May 2011 from http://www.soxlaw.com/ SearchCIO: What is Sarbanes-Oxley Act (SOX)?

  • Network really slow with TL-WN951N wireless card

    - by Sam
    I literally just installed ubuntu and it seems to be working great except the network is deadly slow. I'm running a TL-WN951N wireless card which can download at about 600-700 KB/s in windows but in Ubuntu the max speed it seems to get is around 5KB/s. I guess I should note that my WAP is only wireless-G but like I said, I can get much better speeds in Windows. I'm testing the speeds by downloading files from here: http://mirror.internode.on.net/pub/test/ Anyone have any idea? I saw some people recommend downloading drivers and compiling them myself but I'm really really new to all of this so would appreciate someone babying me through it so I don't brick my computer! Here are the results of lspci -v: 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) Subsystem: Giga-byte Technology GA-EP45-DS5 Motherboard Flags: bus master, fast devsel, latency 0, IRQ 44 I/O ports at c000 [size=256] Memory at e9110000 (64-bit, prefetchable) [size=4K] Memory at e9100000 (64-bit, prefetchable) [size=64K] [virtual] Expansion ROM at e9120000 [disabled] [size=64K] Capabilities: <access denied> Kernel driver in use: r8169 Kernel modules: r8169 05:02.0 Network controller: Atheros Communications Inc.

  • What can I do about rsync of large files killing my laptop's wifi connection

    - by David Dean
    When I run a rsync to backup my home folder over the network like so: rsync -avhz --progress --delete /home/dbdean/ [email protected]:/home/backups/david/ I seem to have problems with my quite large .VirtualBox/HardDisks/Windows XP.vdi file. Occasionally the wifi will silently fail (the transfer stops, and any other network access is broken). If I reconnect the wifi to my network before the transfer times out, it happily keeps going (and other network access is back), but I can't just leave it unattended most of the time, as I have to keep an eye on it. I'm guessing this is probably a bug in the wireless card related to a particularly high sustained volume of network usage, but I'm not really sure where to start with diagnosing this problem so that I can provide a good bug report. Or it could be something else, I guess. Any help would be appreciated. My network card is an Atheros Communications Inc. AR9285, as lspci -k shows: 43:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Subsystem: Hewlett-Packard Company Device 3040 Kernel driver in use: ath9k Kernel modules: ath9k

  • More information about worldwide nodes how to get?

    - by Aubergine
    The context: Six hosts across worldwide were traced over week from UK. Ten thousands of lines to be parsed and analysed. And then I try to find any clue of geographical information and path - from where it jumps where. Then after Austria or Germany(each time different) I have mysterious 62.208.72.6 which in GEO LOC gives me Falklands Islands (which is where my target host is by the way, but before target host I still have 5 other nodes) Then I do whois for this 62.208.72.6 route: 62.208.0.0/16 descr: DE-ECRC-62-208-0-0 origin: AS1273 mnt-by: CW-EUROPE-GSOC source: RIPE # Filtered Why it says Europe now? How to understand this enigma code? I want to confirm more or less whether this is in europe or in falkland islands? But it can't be in FK yet as after next two hosts I get New York? Could you also tell me what does this CW-EUROPE-GSOC abbreviation means. (To preserve your sanity better not google, unless you already know it :-D) And the actual whois for the destination/target host, which completely destroys my head: route: 195.248.193.0/24 descr: HORIZON descr: Cable and Wireless Falkland Islands descr: Via Cable and Wireless Communications UK origin: AS5551 mnt-by: AS5551-MNT source: RIPE # Filtered How is it Via Cable and Wireless Communications UK if two nodes before I was in New York? Thank you guys,
